No I shouldn't, but thanks for thinking of me.

Jorge, I tried to implement setTimeout but I'm not sure if I did it correct (the way you advised me to do): var_this_global = this; var_todo_global = "function_sort(var_this_global);"; setTimeout(var_todo_global, 1200); It only works if I set the value in setTimeout to at least 1200. It works if you click a second time on a column header while the sorting is running. But it doesn't work if you click a third time. Because I have to set the value to at least 1200 it always takes 1.2 seconds until the sorting starts. Stefan

As I mentioned, you don't really have a problem. If your process takes too long (and it definitely does), you need to break it up. Then the clicks (or whatever user actions) will not be "cached" while the engine is waiting for your sort to finish. Solve the real problem and the imagined one will go away. ;) > var_this_global = this; > var_todo_global = "function_sort(var_this_global);"; > setTimeout(var_todo_global, 1200); > > It only works if I set the value in setTimeout to at least 1200.

Do what I told you to do. You can't go wrong that way.
